Cleaning vs. Descaling a Coffee Maker: What’s the Difference?

To help get the best possible brew, it’s important to clean your coffee maker daily as well as descale it periodically.

Daily cleaning helps you keep up with coffee splashes, oils and other residues that are easily removed with a quick rinse or soapy water.

Signs Your Coffee Machine Needs Descaling

How do you know when commercial coffee machines require maintenance?

  1. Limescale in your coffee

This is the easiest way you can tell if there has been too much of a build-up of limescale, as you’ll see some lightly colored deposits floating in your drink.

  1. The machine is taking too long

Is it taking ages for your cup of coffee to be ready in the morning? This could mean that there has been a build-up of limescale in your coffee machine that you need to clean to get it running at optimal performance levels.

  1. The cleaning light is on

In some cases, a warning that coffee machine maintenance is required is simple. Some models of coffee machines have an in-built alert, where a light comes on if it is time to clean up the limescale inside the machine.
